Comment 7 for bug 172188

I don't know if this is related but sometimes when I do "File -> Save a Copy..." the save dialog doesn't even show (I'd say it opens _under_ then main windows, i.e. you don't even see it appearing and then disappearing). The main Inkscape window loses focus and if you click on it the save dialog pops up and gets focus instead. Then if you click on the dialog title (e.g. for moving it), it disappears again under the main window and so on.
This happens only sometimes and I couldn't spot a triggering operation. Everything else works as expected: browsing directories and saving is possible.
I can confirm that native Windows file dialogs are modal too and keep the focus until closed.
Latest builds, Windows XP SP3.
