selection or font problem

hi, i have a font/selection problem: when i select text and expand/reduce the selection, the selected area is not always the same, which results in having 'dirty' regions not repainted correctly. i am using 21.2.19 and my only option is ./configure --with-mule i launch xemacs with -vanilla and the font is the default, i have no clue what the default font is on my X though... (could it be it?) Jan Vroonhof said it could be my font, but then ... isn't xemacs supposed to handle different fonts ? especially the one it gets for 'default' ? so here it is step by step: i open xemacs, i am in the scratch buffer. i go up three times to be on the ;; "If you..." line set the mark, go down to select the line, go one more down to select the two lines ";; If ..." and ";; then" , and then if i go back up to reduce the selection of one line, the selected part "file with C-x C-f," is one pixel larger than the rest of the selected line. so when i delete the selected line with C-w there is a line of one pixel high that stays dirty on the screen. the cursor also leaves a bit of it i just noticed. i understand this is not very easy to explain, but since it is reproducable everytime, i made screenshots that show the steps one by one. i didn't want to send these imaes to the list, so i put them on the web at: http://tanglefoot.lunatech.com/~stephane/xemacs-sel1.gif http://tanglefoot.lunatech.com/~stephane/xemacs-sel2.gif http://tanglefoot.lunatech.com/~stephane/xemacs-sel3.gif http://tanglefoot.lunatech.com/~stephane/xemacs-sel4.gif http://tanglefoot.lunatech.com/~stephane/xemacs-sel5.gif from those screenshots you can clearly see there is one line of one pixel high of selection left, and a part of the cursor not repainted as well. it gets very messy when it comes to editing some serious code, and i've had to learn to put a C-l between all selection commands :( we have the problem on all machines here, with 21.1 and 21.2, it started after 20.4 i must say... -- # Stef Epardaud, # There is no limit to the power of computing ... # Java Defeater # ... except men maybe ? # Earth # Lunatech Research, # Solar System # soon we will quit researching and start finding...
