Well I hope the issue being talked about here is related to mine as well.
When actually in game and I hit Start to go to my inventory, like to equip items, look at the map, or use the in game save. My screen goes black for 3 to 4 seconds, then the inventory opens.
This happens when in window mode or full screen. I have an Nvidia card (listed below) which I have tried several driver version for just in case that was the problem, no luck.
I am using the just released PJ 1.5 final, with all the 1.5 Jabo plugins.
Any ideas on what I might try? (not a big issue, just a bit annoying is all)
