In early Dec 2018 there was a new version of Act Premium. My version is Act Premium Version 21.0.295.0 Update 4. I run Win 7 Pro. The navigation bar on the left hand side will not save your choices of which buttons you want to save there. After wasting much time on the issue, tech support said it is a known issue with no date on a release to resolve this. Every time an update comes out, it causes issues and costs me time. Isn't this software supposed to save me time? Very frustrating but they say there is a fix coming. Know that initially they tried to just tell me that is the way it is and I had to push to get answers. I hope this helps.
