Hi Jayinmaine,
I had had a similar problem with my then new Prophet 6. The issue manifested itself within the first week after purchase and effected the "Bank Program" window,like yours,along with "Effects" and "Clock Sync" windows. Otherwise all other operational aspects of the synth appeared to be ok.
However,I considered this was a sign of a potentially bigger issue that may develop in the future and contacted Sequential. After some suggested troubleshooting from Andy at DSI support failed,the synth was repaired [mother boards?] under warranty.
Not a great start to what was my first poly synth. 18 months has passed since then and all is fine.
Yes,contact Sequential,I'm sure they will look after you.
Hope that helps.
Regards...
