Bug - new folder creation in "save as" menu

[andrewbrick]

In Power BI Desktop, if you select File - Save As, and then create a new folder in a directory within the Save As dialog, this causes windows explorer to hang, or at the very least, causes Power BI Desktop to hang for quite a while.

Hi @andrewbrick, 

1. Please run the 64 bit Power BI desktop if possible.

2. Please check Task Manager to see if the memory usage is high when you do the save as and create a new folder. 

3. Please restart machine then test again. There is a September desktop version released, you can test with this version. 

Best Regards,

Restarted, using 64-bit and the September release. Hang still occurs.  Neither memory nor CPU use spikes when this happens.  It does cause windows explorer to hang along with nearly all other functionality.  It's not completely unresponsive, and it can recover -- it just takes 4-5 minutes.
