Windows starts multiple instances of an application

Please can anyone explain this behavior?

I have 2 PCs both running XP Home and both running PaintShop Pro.
By default JPEG files are opened in PSP.

On PC no.1 if I double click a JPEG in file explorer, PSP opens and displays
the image. If I then double click another JPEG it opens in the same window.

On PC no.2 when I double click a second JPEG it starts another instance of
PSP.

The only obvious difference between the two PCs is age. No.1 originally
came with XP service pack 1 (SP2 was added later). No.2 came with XP SP2.
The processors are different: one has a Pentium 4 and the other a Core 2
Duo.

TIA
Nick.
 
Check you mouse click sensitivity.
Control Panel/Mouse
In the Mouse Properties window, click on the 'Activities' tab
Test the double-click action
Next try moving the 'Double-Click Speed' slider to the right and test the
double-click action again.

I seem to have sorted this out for myself.
I checked the list of file associations and jpeg was in there twice. I
deleted both entries and then reset it to PSP.
All works fine now.

Thanks for closing the issue; good netiquette.
