Power Query pop up windows are transparent and clear. Can't see anything.

[Syndicate_Admin]

I'm having an issue where none of the pop up windows are displaying correctly. I only see a thin outline of the actual window, but the entire content is clear and transparent so i can't see anything. I can move the window around and click the buttons if I know where it is, but I'd like to be able to actual see it. This problem seems to fix itself temporray if I restart excel multiple times or if I go into the editor and display the prompt through there, but the issue will resurface again later.

I'm running  Excel 2016 for Microsoft Office 365 32 bit, version 1902 on a Windows Server 2016 VM.

Does anyone know a permanent fix for this?

Here's a picture.. the thin green line is the outline of the window.

Hi,

Still the same problem here, seems to be only on Power Query over Excel, not over Power Bi.

At the begining, everything is ok and after a while, when I click on gear to edit a previous step (expand fields), the window start to draw borders and nothing more. At this moment, I can't move Excel window, minimize... the only way is Task manager and kill Excel. The dialog box is like in modal mode so we are locked.

Power Query and Excel are very nice, this bug is frustrating.

Thank you.

PS : I'm using last 365 version.

Glad to know its not just me. Sometimes its worked to select the outline and hit the escape key but usually its a job for task manager. I've found it can occur with any of the settings dialogs in Power Query Editor and probably when i have too many files open. 

Only other gripe I have is not being able to naviage through worksheets while in Power Query editor

Same issue here. It feels more frequent and more complicated to resolve. I used to be able to do as others have mentioned, move the transparent box around, move it to another monitor, wait it out, escape it away. However, now I'm completely locked up. Going to have to kill it in the task manager.  I also do not have these issues with Power Query in Power BI, just Excel.

I had previously thought it was somehow related to having an extended display between laptop and external monitor with different resolutions, but I recently had this occur on a different machine that was not connected to an external monitor.

I have found that if I hit escape the blank dialog will disappear. If that doesn't work (in case I have clicked somewhere else) I click tab and then escape and repeat in that order until the dialog disappears. It avoids having to resort to the task manager or wait it out.

Thanks, this did the trick for me.

Hey, all.  I think I stumbled onto a good fix for this issue.  ALT+F4 will close the blank pop-up window.  Then you can just re-launch the editor.  Since it is an infrequent (but regular) occurrence, the 2nd launch has always worked for me.  Hope this helps.

Lifesaver! You don;t know how many queries I've had to rewrite because the only way I found to clear it was to CTRL-ALT-DLT

Thank You!
