Virtual Memory conflicts with Xpress

I have been told that (in Macs) Virtual Memory conflicts with Quark Xpress. My personal experience has confirmed this. Anyone have any input/ideas?
 
I don't use VM since I use Photoshop a lot.
Do you really need VM on? If it clashes with Quark, turn it off.

 
I have my VM turned to double my memory, which is how it should be. I have never had a problem with this. Normally it is more likely to be down to fonts or images, which crash quark.

What is the spec of the machine you are running ? If you can't fix it in 20 call someone who can.
 
I have a G3 Mac, 64 MB ram, Sys. 7.0 Xpress 4.1
(I know, I know, not the best...)

Virtual memory is a huge pain as far as I am concerned. Does it cause confilicts in Photoshop as well? I haven't had much trouble there.

What is the point anyways of VM? Just gimmie some more REAL memory.
 
VM is useful when you don't have much RAM (and you don't). For that setup, you'll be using VM most of the time. Why do you have sys 7.0 on a G3? You should be running at least 8.0 to get the most out of the processor.

Suggest you also invest in a load of RAM - it is peanuts at the moment.
 
From what I can remember apple tells you to run
1 Meg Of VM over the amount of ram that is present
on your Mac unless u need it for apps to run.
Photoshop on the other hand needs a large
scratch disk and should use a lot of ram the more
the better if you don’t have the ram you use VM.
VM slows theMac down because the processor has to
read and write to the hard drive witch uses space
on the hard drive and so does the scratch disk if you
don’t have a large scratch disk it will crash quit
often

I have 1gig of scratch disk just for PS
250 Megs of ram for PS
And a great video card for a 22inch monitor
On a 9600 it runs great with out crashing

cool with the ideas for scratch disk and memory for Photoshop.

As for Quark...

I have personally tested this:
In 6 months of using Virtual Memory (On) and Quark, I have had, on average, 2-3 crashes a week.

Previous to this, I had my VM turned off and had Quark crashes once or twice a month.

Does Quark need VM? And if it doesen't, why does it cause confilicts?
 
If VM is off and Quark crashes once or twice a month there must be something else causing the problem?
I've had occasional crashes when printing to an inkjet from Quark (as if the line to the printer has got blocked with too much data) but not otherwise. I've now got 640 RAM, but I never used VM even when I started in 1997 with 48 and Quark (version 3+) - and, as far as I know, Quark didn't need VM then.
[Primary internal disk, original, is 2Gb. External LaCie 4Gb; second internal disk is 17Gb and this one is assigned as primary scratch disk for Photoshop.]
