Bug report - Adjusting windows

I am finding on both the H4 and FB4 (different showfiles) that frequently when i'm adjust window sizes using the trackball in unlocked mode, the right hand side of the window latches on, so after resizing that edge, if I move the cursor the window continues to resize even though the left click has been released. The only way to stop it is to lock the view. If I unlock again, the right hand edge of the window immediately jumps to where the cursor is on the screen.

I have had this in previous releases also.

Cheers

Colin
