[Bug]: Cursor (Save Menu) not blinking!

Bug Description

When selecting "Save As", or even just Saving for the first time, a Window pops up, with the working file name highlighted in blue, text set in white [SEE IMAGE].

In a large number of cases, the blinking cursor simply does not appear. One can click at various places within the file name, thus changing where text will appear, but the blinking cursor simply isn't there. Makes things very confusing.

This requires closing the "Save As" menu and re-launching, after which, the cursor returns.

IN ORDER TO REPLICATE:

It seems that when you type some new text, there is a short lag, and then the "Preview" window on the right (or wherever it's docked) refreshes. After a "refresh" this bug will activate with 100% probability.
