Hello, For me, LyX 1.5 is unusable because of two bugs.
1. This one is very annoying. Open the attached file crazyscroll.lyx and position section 2 head "This title at the top" at the top of the text window, in the uppermost possible position while still being totally visible. I advise you to use the scrollbar arrows, because mouse scrolling is too coarse (another bug). Now scroll one line upwards with the mouse scroll. It will jump a whole paragraph. This also happens if you use the up scrollbar arrow, but the jump is smaller. 2. Now close LyX and reopen the file crazyscroll.lyx. Notice the cursor movement with the keyboard arrows is mega slow. Then select any text (even a single character) and copy it (my keyboard shortcut is Control-C). You don't need to paste anything. After that, the cursor movement is normal. LyX is now an essential working tool in my community for writing scientific text thanks to your good work, guys, but these issues are causing a lot of frustration to people that try to switch to LyX 1.5. Cheers, Rodrigo.
