Hi,

I’m running the button\_with\_tool-tip example from  
[http://fxruby.org/doc/ch03s04.html](http://fxruby.org/doc/ch03s04.html).  
Hovering over the button produces no tool-tip. Ditto for a couple of  
other FxRuby button/tool-tip examples.

The weird thing is that FxRuby tool-tips were working yesterday.

I made one change to my system today: I changed a Registry datum: I  
changed EditFlags from 8 to 0 in HKEY\_LOCAL\_MACHINE\SOFTWARE\Classes  
\rbwFile. That change enabled the Advance button in the Folder  
Options dialog of Windows Explorer for the filename extension .rbw.  
In turn, I was then able to assign the IDE “SciTE” to an Edit entry  
in the context menu of an .rbw filename in Windows Explorer.

I just brought up Excel and Word to confirm that the tooltip mechanism  
of Windows is not broken, so I don’t think it’s an OS problem.

I’m running WinXP/SP2 (up-to-date with Microsoft updates) and Ruby  
186-26\_rc2. I’m using Prev-X for virus protection (the best in class  
on the planet, IMHO). I don’t visit any virus havens like porn sites  
and encryption-cracker site, so I don’t think my system is infected.

I’m out of ideas. Any suggestions on what to try?

Thanks in Advance,  
Richard
