ve not showing correctly

[dig]

Hi guys,
I have the following problem for which I would appreciate your input. I have a vizard 4 script that runs just fine on a pc connected with an HMD, an intersense, and a light license. I transferred the script to our main computer with a development license to create an .exe. However, when I run the script on this pc the VE is shown side-by-side on the computer screen (i.e., the screen is split in the middle and the VE is shown on each side). When I create the .exe this side-by-side effect remains in the resulting file. Notably, this effect does not occur with other VEs that we have on the development pc. Any ideas on what´s going wrong?
Thanks in advance,
marios
