I've been a happy and experienced user of TeXmaker, on 10.04 and earlier, for many years. I've now upgraded to 12.04 and installed the 12.04 version from the Software Center.
After installation, my first attempt to use TeXmaker brought up the usual window containing the latex file. Which, with <F2> seemed to compile normally. On doing <F1> to bring up a display of the .dvi file (which I assumed would have been postscript), however, things went awry. There MIGHT have been a PDF display on the far right side of the window containing the.tex file. But somehow I never really got to a good display of that.
And, after that, now when I start Texmaker on a .tex file, the window that used to come up now disappears in a series of horizontal bars that migrate down to the bottom of the screen and disappear. Has anyone else seen that kind of behavior?
I have removed the TeXmaker app, using both the Software Center and Synaptic, then re-installed, but this does not cure the phenomenom of the disappearing bars that might have been the startup window.
Any help out there?
