Weird button behavior on print preview ribbon in Access 2007.  For some time 
now, I have noticed that occasionally, when we open a report in print preview 
mode, the print button on the print preview tab in the ribbon is dimmed and 
not enabled.  This happens on all our computers, not just one.  It happens 
about 25% of the time we open any report.  The workaround has been to right 
click and use the built-in shortcut menus to print from the preview.

I finally got around to writing my own ribbon xml and having the users open 
the application in runtime mode to lock things down a bit.  When I wrote the 
ribbon xml, I specified the enabled="true" attribute on the print button, in 
the hopes that this would sort of force the issue.  Unfortunately, it did not 
solve the problem.  Even worse, by forcing the users to open in runtime I 
have disabled the built-in shortcut menus.

I don't really feel like writing a bunch of shortcut menus via the command 
bar capability that seems to be discouraged in 2007.  I'd rather figure out 
the root cause rather than keep patching around it.  Any ideas?  Is this 
possibly a documented 2007 bug?  I read somewhere about disappearing ribbon 
buttons, but this seems different.  I did experience certain buttons not 
appearing on the custom ribbon but solved by forcing visible="true".  PS - we 
are using 2007 SP1.

Thanks.
