Cannot Drag Icons from Desktop to TLB

Suddenly in Windows 10, I cannot drag anything from the desktop into a TrueLaunch Bar. When I drag it and stop in a TLB, nothing happens. This has not been a a problem until today.

I am using Windows 10.0.10586 and TLB standalone 7.3.3 beta 64bit.

This is still a big problem.

Do you see the tip and "insertion mark" when you drag icon over TLB?

No. I see a circle with a slash through it. But I will say that this problem is intermittent. It happens most of the time, but rght now, for example, no problem. I think this is a generic problem with Windows 10. When it happens, I also cannot drag and drop files to programs, etc.
