Changing the size of a family does not does not change the size of the family

When I change the 1000 in 3600 the Apply button stays grey and after a few moments it changes back to 1000. Sometimes 1 time, sometimes 10 times. See the attached video. When I have Enscape open at the same time the opening changes in Enscape but still not in Revit....??? (it also happens when Enscape is not open, I crossed that off the list)

Also when I want to change one family into an other I can't select the new family. The pulldown closes before I can select. Again and again.

Closing Revit is the only solution. Restarting my PC an even better solution.

• Does it happen only in 1 particular project?
• Does it happen in many different parameters in different families for you?

[ron_adst]

It happens from time to time. Different projects. 3 weeks no problem, then days with a lot of frustration.

Mostly from the properties menu.

Different Families.

Materials I can't change from the Propertiesmenu. That wil almost always fail.

I wonder if this might be not software, but hardware issue because it looks like lagging of processes. I heavn't experienced that problem before. Could you check in task manager if your system is not overloaded while this problem occured?

[ron_adst]

We looked at it but that is not the problem.

Make 'em Instance Parameters.  

[ron_adst]

they are

The problem is sometimes. For weeks no problem and then 2 days in a row complete frustration.

[ron_adst]

We have 10+ Revit stations here at the office and none of my co-workers has the same problem.

That is an asnwer............. What is wrong with my PC?

[AutoCAT95]

If the PC is guilty, have you tried bringing back default Revit settings or reinstal program?

[ron_adst]

I have a new PC and still, from time to time I still have the problem. 

Solution?... Closing outlook.... Why does that matter?
