Perhaps someone can throw some light onto what is fast becoming a severe annoyance rather than an 'issue' ?!
Was running current version of Barca Pro on my old machine OK under Windows XP. Machine expired as in died, so I got a new PC with bells'n'whistles etc but it came with Windows 7 Home Premium (64-bit)

Anyway, started to install all my old software including Barca Pro (v 2.8.0.4400) and all looked OK.
Now, have a really niggly problem with Barca now, in as much as in the folder pane on the left, the scroll bar goes transparent and shows whatever is under the Barca window ... be it another prog window or the desktop !!!!!!!!
Tried a re-install but get the same problem ! ... so to illustrate the error I've taken a screen grab ... and I've highlighted the transparency inside a red outlined box ... see below ...

Anyone care to offer a 'fix' ????????????????
