Yep, i think you're right. now the question is, can i distribute that dll with my app?


>Looks like RichText editor itself is implemented in the separate DLL which is a part of the WIndows. The RichTx32.ocx is just an ActiveX wrapper. Take a look at http://support.microsoft.com/default.aspx?scid=kb;en-us;Q308310 and http://msdn.microsoft.com/library/default.asp?url=/library/en-us/shellcc/platform/commctls/richedit/richeditcontrols/aboutricheditcontrols.asp.

>>yes, my app installes 'my' activeX, and i checked on the windows 98 machine, the RichTx32.ocx in the windows system folder is the same as the one on my winXP machine (at least the date/time of the file).

>>>My guess would be that the RichTx32.ocx on Win98 is earlier version than on WinXP. Did you try to install the WinXP version of the control on Win98?
