Prventing multiple instances of an app
OS : W7 64-bit Home Premium. Application : Paintshop Pro 7. If I want to look at multiple images in PSP, I can either open PSP and "File > Open" each one, or double-click each one in Explorer. In XP both these methods resulted in a single instance of PSP and the ability to switch between images via PSP's "Window" menu. But in W7 the second method spawns a new instance of PSP for each image, hogging resources. Is this default W7 behaviour? Or just a quirk of running an old 32-bit app? And above all : can I change it?
