I'm using fvwm 2.6.3 under Gentoo. In the last couple of days, I've noticed that the dashed lines separating the desks in the FvwmPager display disappear when I move to another page. I can get them back by restarting X, but then they disappear again when I move off of the initial page. I have made no changes in any configuration files. Fvwm was compiled on December 13.
My ~/.fvwm/.fvwm2rc says: Xinerama off DeskTopSize 3x3 Module FvwmPager * * Style FvwmPager Notitle, Sticky, WindowListSkip, StartIconic *FvwmPagerIconGeometry +0+0 Module FvwmAuto 500
