Encountered a few issues while posting to forums

FYI: I ran into few issues while posting on the forum described below.

While typing the post the browser window (not the screen) suddenly went dark with an overlay and I could no longer type. I assume the connection was briefly interrupted and the auto-save draft feature was attempting to prevent more input until it could be saved. I waited a few moments and verified the connection was working but the forum page never recovered and I had to refresh. I could not copy the text (without resorting to a developer console) so it was frustrating to have to refresh.

Fortunately most of what I typed was saved as a draft, but this brought to light the second issue. I loaded the draft and finished my post but was unable to post. It said the category is required, but the only item in the category dropdown (Mac) was disabled and I could not select it. I had to copy the text and paste it into a new forum entry.

Finally, I was going to add an image attachment to this post to show the category error, but I can't do that either: the popup doesn't appear when clicking the Image icon in the toolbar, only a shadow of what looks to be the top border appears.

Minor issues and I'm sure this is not your highest priority, but annoying for a customer trying to help by reporting an issue. I'm using Chrome 60.0.3112.90.

Thanks.
