Sybase Central 11, 12, & 16 Crashes When Adding Column to Table

Hi All,

I'm hoping someone can shed some light on this issue I've been having with Sybase Central across multiple versions, multiple machines, and multiple databases...

Often, when I try to add a column to a table, or even modify a view, Sybase Central crashes. 

The stack trace indicates: java.lang.AssertionError: Unexpected table type: 5

I've included a screen shot if that helps at all along with crash file.

I have no problem adding columns or altering views from within ISQL.

I've done a fair amount of searching but have come up empty.  Any idea what I might be doing wrong?

Thanks,

-Brian
