I have Visio 2000 installed along with MS Office 2000 on a Redhat 7.3 machine running Crossover office 2.1.0.
I am unable to save or load Visio format files at least 90% of the time. Whenever I try to save or load it just vaporises. :-O
I can usually save in wmf format, which can then be re-imported, although it's messy and one loses a lot of features. ☹️
For me this app does not rate as silver. Probably not even bronze. BTW exactly the same happened on cxoffice 2.0.
