Photoshop Save Dialog CAN'T SHRINK?

Question

So, I was using Photoshop, and went to save a document, when I stretched the save dialog bigger, and randomly could no longer shrink it. The same thing happened in Illustrator as well.

Details: I'm using Windows 10 with multiple desktops. I tried restarting the programs, and my computer - neither did anything. Is there some settings file I can clear?

Answer 1

Well, I haven't necessarily found a way to make it shrinkable, but I did at least find a way to restore it to normal, as long as I don't stretch it big again.

It's another Windows 10 error. This site gave me some direction:

The window dialog sizes can be found in the registry in the following key:

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\ComDlg32\CIDSizeMRU

Deleting all the entries except (Default), 0, and MRUListEx will reset the window dimensions to default, including those of Adobe's save dialogs.
