Dear all, a few days ago I upgraded FVWM to 2.6.8 and was quite happy, but for FvwmIconMan failing to update when windows are opened/closed. Quite strange, really.
After Lucio Chiappetti helped me with a working example, I was able to find the problem in my fvwm2rc files. For some reason, the lines Style * IconTitleFormat %n Style * TitleFormat %n were in fvwm2rc and they messed up FvwmIconMan for some reason. Deleting those lines made all work again. I am not sure about those lines, maybe I inserted them myself sometime in the past or fvwm-convert did it (but probable not). In any case, I wanted to report what happened and thank Lucio for the help! best regards, joao batista
