Why is Basecamp using 3GB of memory?

Hi,

I paid £20 last night and downloaded a section of mapping using BirdsEye Imagery. Trouble is, Basecamp is now using 3GB of memory and the application is unusuable. The rendering of the map tiles when I zoom in and scroll is a joke.

Is there a fix for this issue or do I contact Garmin for a refund.


Thanks
