I notice that when I have the Toad Beta up and using it for several hours that I slowly use the use of Copy-n-Paste in applications.
After an hour+ the Paste action, Keyboard Ctrl-V or mouse select of paste slows down and eventually stops. This is true for other applications on machine. I can’t cut and paste between email and text editors etc etc.
If I kill Toad and wait a while the cut-n-paste functionality returns.
I have a Windows 7 64bit Dell Latitude E6420 with 16 GBytes of memory. I upgraded the memory from 8 GB to 16 GB thinking that was the problem, but the problem soon returned.
I have no idea how to tell you how to reproduce the problem. I have many browerse and applications running at the same time, and typically have 9GB of memory in use according to the task manager.
