The problem is that, when mouse hovering, no text painting should be needed, only background. But, because of current architectur where text is drawn _after_ background, we are forced to do the text painting. Changing this (using text on transparent background painting) basically needs a rewrite of rowpainter hence a 1.6 business). Now, in case when mouse hovering hapens just after a SinglePar update and at the same screen location, grey areas are drawn before and after the current paragraph. I am not sure I am clear...
No. :-) But I have not experienced this bug for a day after I applied the patch, so I guess the patch (and your analysis) is correct. Bo
