so, this has started happening lately: every time I make a left-click on any item that accepts left clicks (panel, frame, window, desktop, taskbar), the click would somehow get remembered, and further left clicks would work only within this 'item'. I can unlock this with a right mouse click on the same item, only to be gracefully rewarded next one 'free' left click. If the item does not accept right another solution is to close it's window using the keyboard. This has effectively rendered my computer unusable
Any ideas? I have tried resetting the KDE desktop to default, tried another mouse, even tried reinstalling Linux mint, but the same problem appears even in the installation process! In LiveCD of other distributions everything is OK.
Using Mint Gloria, KDE 4.2.4.
Any help would be appreciated!
