slow menu response

I've noticed that dialogue box response in 6.4 LE has slowed way down:i.e. When entering a new track name there's a 15 seconds delay before typed letters actually show up in box. Anyone else have this problem?

I am having the same problems. Last night I was trying to add some MIDI to a track, and everytime I would add MIDI with the pencil, my screen would lock up and it would take at least a minute for it to go back to normal. Also during MIDI playback it would play for a few seconds and totally freeze. Anybody got any suggestions?

Did you find any information about this? I have the same issue on some sessions. I have heard about the CPU overload that can happen with very low audio levels in some plugins. The work around is to put a dither ahead of the plugin. Thanks in advance.

my guess on this would be ram

I have 1GB of RAM. Though I am running both Reason and Sampletank and UAD RealVerb. It is a strange slow down in speed. It only happens when some menus are opened. Otherwise it works fine.
