I still use it a bit, in simple contexts to be sure, but I do find it useful. Others think so as well. I think TkAgg is probably the most commonly used backend in Matplotlib. I wrote a single Matplotlib-using program which plots columns from CSV files. I use it almost daily with no problems. Again, I use the TkAgg backend by default. So, does it have problems? Almost certainly. It seems you've encountered some. If you want to see something change though, just screaming at the developers is almost certainly the least productive thing you could do. Here are some things you *could* do: * submit some bug reports * review patches related to the problems, assuming there are some * write some patches for the documentation adding warnings about sketchy bits Skip
