Cubase 7.5.40 / Video Player Window Closing.

From reading up this is an issue which has been around for about 5 years atleast and I cannot find any fix anywhere.

-Using Cubase 7.5.40 and Reason 7.12 in Rewire mode.

-Working on post-production project.

-Video Player Window in open state on 2nd monitor.

-Click over to Reason on the 1st monitor, in order to make some edits on Reason, whilst hopefully the video will be playing on 2nd monitor.

-Video Player Window closes itself… No matter if its in maximised view or minimised state… anyway possible… the video window it closes… making it impossible to sufficiently work on post production projects on Cubase in Rewire mode.

Please tell me there is a way to fix this ridiculously simple and ridiculously annoying issue!
