I'm using PS version 12.1x32 (CS 5.1 Extended) and recently i've been getting some erratic behaviour when creating clipping paths/using other tools.
For some reason, as I'm creating a clipping path, the results of my work aren't showing up unless I either change my view setting or changing my zoom level (which leads me to think it's a refresh problem). Even when I'm done with the clipping path and I move it around, it still doesn't update, only showing the last position (see screen grab below). Has anyone come across this behaviour before and is there a solution? Also, when using other tools, such as rectangular marquee (but not limited to it), my cursor dissappears whenever i'm using the tool. It's a bit annoying to be honest...
(note position of path outline in preview window vs actual position in path panel thumbnail).
It seems that OpenGL being enabled had something to do with it. It's working now.
