@ambershark Thanks for the input. I was afraid the window manager changes might be the issue. We are using KDE as our window manager. I have limited control on what I am allowed to change unfortunately. For now, I will likely move forward with work around. Since the applications dialogues now appear in the task bar, there is little downside to minimizing them. The issue was they would simply get "lost" when they were minimized. I was able to remove the maximize button by setting fixed size restraints on the dialogues. I will update the post if I ever figure out how to get the KDE settings and the Qt Window Flags to play nicely together. I have been investigating the kwindecorations settings, but had no luck yet.
