I experience frequent freezing of HyDraw when I switch the grid snap mode (F9) or the ortho mode (F8). How can I resolve this?

The issue can occur if you recently updated Windows 10.

To unlock HyDraw from freezing, Click the task bar. (no need to press CTRL+ALT+DEL)

 

To solve this issue, in HyDraw CAD:

Set TEMPOVERRIDES variable to zero. (type TEMPOVERRIDES from command line, press enter, TYPE 0, press enter).
