"Choose gallery" not working in Chrome

Hi,

Today I encountered a frustrating problem that was however easy to solve but I thought I should share it in case someone else experiencing the same.

I was going to upload a picture to one of my older galleries (I have at the moment 163) but I couldn’t choose gallery. The “move/arrow/grey-thing” didn’t work.

However when I changed from chrome to firefox it did work.
