Strange sluggishness since 5.1 update.

I wonder if anyone else is experiencing this, but since I installed 5.1 on my Mac (OSX 10.3, 400mhz 384meg RAM), I have been experiencing a very sluggish user interface. I realize this problem was cleared up in an update before 5.1, and I was not having the problem then, but now double clicking does not work most of the time, clicking on fill in fields for numbers is very slow, and backspacing in those fields takes forever. Also playback has dropped to 1 to 2 frames per second for the simplest of animations, where I was getting 12 frames per second before, even with allow frame skipping turned on.

Rendering speed seems decent though.

Maybe its a problem with my Mac, I don't know, since I have not heard anyone else having this problem.

Hmm, that's very odd. I'd like to hear if any other Mac users are experiencing this...?

Have you tried looking at CPU usage? Are the text fields really slow to respond when you first start up Moho, or after it's been running for a while?

Someone in another thread suggested I shut it down and restart. I have just been keeping Moho running continuously, I was able to do that before. Anyway, I shut it down, but did not check its cpu usage first, and restarted it and now it is all normal again. I can double click, the fill in fields are fast and the frame rate is back up to 12.

I'll leave it running again and I'll check it periodically for CPU usage.

I can confirm that MOHO does exactly the same thing for me. I methodically quit and reload the program when ever I notice things slowing down, which probably averages every half hour or so.

I'm running MOHO 5.1 on a a dual 2 Ghz PM with 2.5 GB Ram and OS X 10.3.8.

This has been a problem all along, not just with 5.1. Quitting and restarting is just part of my routine now, and I'm not really that bothered by it - although, obviously, I wouldn't miss it if I didn't have to do it anymore! I figure LM will get around to addressing it eventually, and I still love the program.

It continues to be strange. But yes I love the program too.

I restarted it and used it a little bit, no sluggishness, frame rates at 12, which is normal for my laptop.
I left it alone, came back and played again, frame rates were about 10.
Set allow frame skipping to test something (the frame rate went up to 23, which is good), then set it to not skip frames again. played agan and got about 6 frames per second.

Left it alone for two hours, checked the CPU usage and it was aprox 20 percent just doing nothing.

Left it alone for an hour and the CPU usage is back down to about 5 percent. Frame rate is back to 12. Left it playing while I typed this message and now the frame rate is 6 again. But I can still double click good and fill in fields are fast.

I hope this description helps. Anyways the workaround for when it really goes south seems to be just restart it, which is not a problem for me.

PS. it is sitting idle now with a blank project and it is using about 43 percent CPU.

it don't bother me too much either...
But well my client is behind me when i work on his mac
(i use windows or linux for my own projects!)
And it's bad to show him that i need to restart
We are preparing a 5 month prod... wonder if i should instal linux on his mac but i heard that there are some limitations.. (audio and quicktime)
The audio is almost unusable in moho actually anyway. Couldn't it be done without quicktime (using, say, sdl) and linux compatible?
Just some though to convince my client to use moho for big prod!
Of course the best is an optimised version for mac but i cannot wait very long!

best regards

Another issue to installing linux on the mac would be binary compatability. It would appear (and LM can correct me) that only linux x86, not PPC, is currently supported by moho.

That's correct, the Linux version is x86 only, so it won't work on PPC Linux.
