Not really a Basecamp problem (at least I don't think so) but can't think of where else to post this :)
I run BC (same version 4.0.2) on my laptop and desktop.
On my desktop in BC if I open a geocache in the top right hand corner there is a blue link to the cache webpage. Clicking on this opens the cache webpage. While the blue link is also there on my laptop clicking it does nothing.
I've checked my IE settings and they are identical on both PCs.
Anyone any idea why it works on my desktop but not my laptop?
