Here one for the record.
When working on my app and zooming in/out, the mouse scroll sometimes ONLY permits me to zoom out but not in.??!!
I can move around by making bumping...yes...bumping either the top, bottom, right or left sides of the screen.
Eventually, I clean the caches, force quits on XCode and Safari and then reboot. Sometimes, this fixes the problem. Other times, I have to force quit several times and then it fixes.
I wonder if there is some overflow in the memory which causes this behaviour?
Anybody else experience Mouse Scroll semi-freeze on zooming?????
