This is another issue that has been happening for a while before the betas.

I'm wonder if you have SlickEdit maximized and/or the dialog is showing up being a SlickEdit window? It sounds like a modal dialog box is running which is why SlickEdit is still responding to key strokes/events.

Yes, I work with the SlickEdit window maximized on the middle monitor. The “Reload Modified Files” dialog is modal, the “Find and Replace” isn’t.

It doesn't matter whether the launched from dialog is modal. The dialog being displayed for "Diff select" is modal. The Clipboards dialog (Ctrl+Shift+V) is also modal. The modal dialog is probably hidden behind the SlickEdit main window. If you unmaximize the main window and maybe even move it around, you should be able to find the modal dialog.

Clark is right, for the 2nd scenario with "Find and Replace", there is a "Select Text to Paste" window in the gnome looking glass window list. Unfortunately, I'm not smart enough to tease more information out of the lg tool at this point.  With gdbus I was eventually able to display the frame rectangle for the hidden window, and the x,y,width, and height was sensible (upper half of the left monitor, x=y=0).

Not sure if this is helpful, but the clipboard window usually shows up on the screen to the left of the slickedit window when I use if from other contexts, though I'm not sure if that matters much here.  I moved it to the same monitor, restarted slickedit to save the new position and it made no difference for the problem.   I've also tried using the system Qt libraries, but that doesn't help either.

Similarly, there seems to be a diff window hiding somewhere too for the first scenario with the "Reload Modified Files" dialog.

Try the Qt 5 installer. I have noticed that it can make a difference. For example, I use Linux Mint because I like the desktop manager. With Qt 4 version, when you have modified files and press Alt+F4 (has to be Alt+F4), the dialog prompting to save modified files ends up behind the main window. This doesn't seem to happen with the Qt 5 version.

The v28 Qt 5 beta 3 installer is here:

Thanks Clark, the problem is not present with the Qt5 build, the dialogs show up as expected now.

That said, there an really annoying issue when closing the "Find and Replace" dialog, the cursor state doesn't get restored.  What I mean is that I'm using the "vertical cursor" style with a 1Hz blink rate, so when the "Find and Replace" dialog pops up it turns into a block cursor and stops blinking, so far so good. However, when I close the dialog the cursor remains in non-blinking-block-mode. I can work around the issue by clicking on the "Find and Replace" dialog with the mouse, or I can bring up the "Select Text to Paste" dialog while "Find and Replace" is open.  So, it kind of seems like the dialog isn't fully activated, in focus or something.
Update: After installing system updates and rebooting the problems went away, so please ignore.

Window management on Linux is such a joy. ;-)

The problem with the "Find and Replace" and the "Select text to Paste" dialog happened with the Qt5 build while running with some malloc debug enabled (env.var. MALLOC_CHECK_=3; hoping to more useful info on a spurious 'smalloc(): unaligned fastbin chunk detected' that has triggered at least twice). I suspect the heap debugging code slow things down a little, hinting at some async event issue somewhere (could be in the window manager too ofc).

The cursor restore-and-resume-blinking problem has also popped up its head a few times today, once even without enabling the heap debugging.
