Hi Jon,

Since v3.1.9 I sometimes get the attached message.

Usually this problem disappears after a restart of DisplayFusion. A colleague of mine has the same problem. The system should be quite identical.

Also this message came up:
[tt]See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:



When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.[/tt]
