Garbage in Method definitions (UML Operation Properties)

[gnuman1]

Hi all,

I seem to have a major problem with method definitions in Visio. In UML
Class Properties, one may click on Operations and then Methods... to
view all methods defined. It is possible to change them there as well.
For example to define method B,

{
blah++
}

Clicking OK and then Methods... reveals it is stored properly. But,
click on the B then Peroperties, Method and then change the method to

{
blah++;
}

After click OK, and then the Methods... button you get

???????
Paramet

as the method body!! Huh?

Method bodies defined in the UML Operation Properties dialog seems to
be always corrupt. Has anyone seen this before? Any fix for this error?
