Adobe Acrobat Reader DC - hang with Save/Edit features.
I installed the latest Adobe Acrobat Reader DC with version 2021.007.20099 and noticed that it always get hang when using the Save-As button (with blank box) and the rest of buttons features such as "Edit PDF", it pop-up box was blank. Try several solutions found from this Community Forum (which related to the Save - Blank box issue) such as disable the "General - Show Online Storage When Saving File", this only solved the Save blank screen, but the rest of problem with Tools - Fill & Sign, the Signature button click but entire screen turn black and hang there.
I tried restart the PC, it back to normal for first time and once closed the software, and re-open it, the problem continue again. I even try to "Repair the software" also similar result as earlier method. I tried closing the RdrCEF.exe through the Task Manager screen and restart the Adobe Acrobat Reader DC, sometimes it work but most of time it doesn't. I suspected this latest version really not stable and got bugs need to be fixed.
Do anyone know what's going on with this version and how to get it fix, or really have to wait until the next update version?
