Cannot connect any objects in UML diagrams

[SimplyGed]

I've got a Visio document containing 56 UML diagrams (class, sequence,
package etc). I've been OK using it up until a day or 2 ago, and now I can't
connect anything to a connection point.

I've installed SP2 and upgraded to Office 2003 (inc SP's) but to no avail.
I'm running Windows XP SP2, all service packs/upgrades installed.
I'm using the version of Visio that comes with Visual Studio 2003 Enterprise
Architect.

Any help would be appreciated as I'm at a loss what to do now !!

Cheers

OK. I've found my own solution.
In the Tools->Snap and Glue window, under Currently Active, the Glue option
had been unselected. Once selected, everything is working fine again.

D'oh !
