Win not breaking correctly on breakpoints.

Is there anyone else out there experiencing problems with breakpoints on Windows? I have set breakpoints. It stops on the breakpoint and sends focus back to Xojo but the screen is blank and I cannot step through the coding. I am on Win 10 and the latest Xojo build. Have tried rebooting, clearing breakpoints and nothing works. Thanks for any help.
