in build 1525 the syntax highlighting seems to be broken. Each keyword which is defined to display in bold has a black background and a very dark foreground color so that the source is unreadable. I have this problem with nearly each EAP build since R# 2.0 . Normally i can fix this by going into the VS Options dialog and open the "Fonts and Colors" section. After this the syntax coloring is as expected. But in the current build this will not work. As the R# options dialog is also broken i don't have a chance to disable R#'s syntax coloring. What i also noticed is, that there are no Resharper entries in the "Fonts and Colors" dialog of the VS Options.
I saved the registry entries for syntax coloring some time ago. When i merge the saved settings and start VS everything is ok. When i open the "Fonts and Colors" option dialog the registry entries for R# syntax coloring are deleted.
