I have been alt-tabbing out of PoN to read the manual, check the forums, etc... After about 12 turns (but several hours of running), the UI became so unresponsive that I had to shut down PoN and restart it. I would click on buttons and the window would not open.
I saw people mention that they alt-tab out since turn resolutions take a while, so I figured it would be ok for me to do so. Are there any known memory leaks from alt-tabbing, or after the game has been running for several hours? I'm not sure what caused the slow down.
Thanks,
Rob
