Can't add or edit tools in any library

I’m running the latest relese build of Millmage. 0.8.00 R19. At first, I could edit tools and add new tools. Now can’t edit any tool in either a new or exisiting librairies. As soon as i choose EDIT from the menu, the OK button is greyed out preventing any updates to be saved. I also don’t understand why some tools have grey bars behind them. Thank you for any assistance on this!

You’re running the RC, which is not the latest - the latest is the release, and this has been fixed.

The tools with grey backgrounds are Imperial tools, and the others are Metric.

Thank you!

i am just beginning with the “trial” 0.9.01 version… have the same problem about editing tools…

Trial license. The version you are “trying” is the full Pro version. Once the trial is over, then you enable the Core or Pro version with a license purchase.

Did you click on the Apply Changes button at the bottom first?

yes obviously. in reality it did not affect every kind of measure editing… tools, material, drawing.. nothing. but fortunatly solved re-installing the program. now everything works!!! thanks a lot!!
