Hi,

Maybe my computer is just too slow. 466 G4, OS 10.3.9, 768 MB physical RAM.

It's paradoxical, though. On some tasks, Rev is scary fast. Like lock message, lock screen, go to 1 card at a time in a big stack, looking for something specific. Practically instantaneous!

At other times...

I've complained before about the nightmarishly slow find and replace window -- if the stack has, say 300 cards, 100 fields per card, plus that many more buttons per card, and a lot of script.

Today, I'm asking about something else. I often type quite a lot of text into a single scrolling field. Like if I'm keeping a lot of notes on one topic in some stack.

Sometimes it works okay. At other times, there's a short delay from keyboard to screen. Sometimes the delay gets longer and longer, until the thing is just useless. Different things seem to get it moving along again. Saving the stack doesn't seem to do much -- maybe a little, sometimes. Exiting all other applications doesn't seem to do much. Saving and closing other stacks... I'm not sure. Inconsistent results, maybe. Quitting and restarting Rev usually helps. Whether I'm inserting text into the middle of a paragraph versus typing at the end of the field seems to make a difference.

Bg and stack scripts are one giant scrolling field, it appears. The same thing happens sometimes, but not always, when working in a bg or stack script with lots of handlers, lots of text.

What do I need to understand about this phenomenon? What's the trick to making it better?

Oddly, nothing like this ever happened in hyperCard. Same computer, older OS. Yet Rev is supposed to be faster than HC, at least in some ways, and OS X is supposed to be faster than OS 9.

I've heard that the right graphics card can speed up some Macintoshes running OS X. I'm told the graphics card will handle most of the number crunching necessary for the Aqua GUI, relieving the CPU and RAM of this chore. Would this help in my situation? I don't know much about my graphics card. It shipped with the machine. ATY,Rage 128 Pro, it says here. 16 MB VRAM. I don't know if that's a lot or a little.

Would more physical RAM likely make a difference? I have an "activity monitor" utility. Rev doesn't seem to be maxxing out the RAM, even when other applications are running. But what do I know? Not much.

Thanks in advance,


Tim
