Graphics Applications Fighting Over Each Other?

[Aaron]

I've got the following installed:

Adobe Photoshop 7.1

Macromedia Fireworks MX

Jasc PaintShop Pro 7.04

And this is what happens in this order:

Open PS7 first

Fireworks opens fine

PSP7 refuses to execute

Then starting again with no gfx applications running (again, in order):

PSP7 opens fine

PS7 refuses to execute

Fireworks opens fine

and the last combination...

Fireworks opens fine

PS7 opens fine, after 20 secs of idling... it crashes and closes down.

PSP7 refuses to execute.

what the hell is going on?

Why are you running them all at the same time?

There's specific different features that I like in each one, one feature can be easier than the other.

Anyway, I rebooted and all is ok. Strange though.
