LoadRunner 11(Vugen) application running on a secondary device bug

I came across an interesting bug in load Runner 11(no patch).

Component
Vugen
Dell monitor - Secondary device

Issue
If you try to compile(Shift+F5/F5) a code that has an error, the whole code disappears. Same behaviour is observed when you open a script. This happens if you have the Vugen application on a secondary device. This issue does not occur when vugen application is running on primary device.

I have a Dell montior(secondary device) attached to Toshiba laptop(primary device).

Before compiling the code

After compiling the code


Solution
Follow are possible workarounds:

• Resize the vugen application



• If you have multiple scripts open(different tabs) then switch back and forth between them


• Run Vugen application on a primary device
