I only noticed this after updating to Accordance 10.4.1, but I seem to have the same problem in 10.4.0. My workspaces, which originally were created several weeks ago, are locked most of the time I can't resize the panels or even move them around. Sometimes I can grab a panel and resize it- say, increase its width; but when I try to decrease the width, nothing happens.
I guess I experience this randomly, but it occurs about 90% of the time. Sometimes I simply click on a panel with my mouse, and the panel moves itself to a different location in my workspace!
I guess I may have to go back to 10.3.x since I don't recall experiencing this before 10.4.x. Any suggestions?
I have attached a workspace. I am using Windows 7 SP1, updated patches.
