What steps will reproduce the problem? 1. Open two .nbk files (two tabs open in KeepNote) 2. KeepNote UI becomes extremely laggy until closing one of the notebooks

Laggy meaning application sometimes locks for 2+ seconds when alt+tabbing to keepnote from another program, typing on a note halts frequently for a second or two at a time (continue typing but nothing shows up, then catches up later), etc.

What version of the product are you using? On what operating system? KeepNote 0.7.8 Windows 7 x64 Service Pack 1

Erp, I downloaded keepnote just this week but somehow got 0.7.8 instead of 0.7.9

0.7.9 works perfectly, this bug should be closed. Sorry!
