[Ti] Weird Screen Behavior...

[b]

According to John Pariseau:

Hi John,

I'm wondering why you have the ATI Monitor in Login Items. never 
heard of that before. My copy is in the ATI Utilities folder in 
Applications/Utilities. Does it actually launch and do anything?

Also, what 'latest video update are you referring to?

Reason I ask is that I run Photoshop 7.0.1, fully =loaded with about 
every plugin known to man or beast, and it does full screen renders 
and previews, without a hitch, unless I use the DreamSuite plugin, 
which needs gigs of RAM, so i use as standalone. But P-Shop gives me 
no problems.

The i GB of 'free' disk space isn't enough. The OS likes at least 20% 
free, preferably contiguous [i.e. non-fragmented] space to work with, 
and Photoshop likes a 'fat' 'scratch' folder, or space, also.

My suggestions:

1- Off-load enough files, applications, or whatever, to bring the 
free disk space to at least 20% of the total drive.

2- Run the Disk Utility on the drive, from a separate partition, or 
the Install disk, if you have only one partition.

3- Delete the ATI utility in your Login Items, and let it reside in 
the Utilities folder with the other ATI utilities.

4- Optimize your drive, after making adequate space on it. Use Norton 
Speed Disk, or DiskWarrior Plus Optimizer, if you have the DW CD.

Remember, Photoshop looks at the startup drive first, in order to 
form a 'scratch' disk. It's all in Preferences, as is the memory 
allocation. On my Ti 667, with 1024 MB Ram I have Photoshop set to 
'max' out on 459 MB RAM.

Lots of free, contiguous, [again, meaning not fragmented] drive space 
and a ____load of RAM make Photoshop very happy.

Good luck.
