Thank you for reporting this problem, your points were updated.
We managed to fix it right away and will upload the fix on our site later today, together with the fix for the installation issue, mentioned in the Available for download: SP1 of r.a.d.controls for WinForms Q4 2006
Please, note that the version numbers of the build will be the same (Q4 SP1 vs Q4 SP1), however the DLL versions will be different (18.104.22.168 vs 22.214.171.124). The new version has a slightly updated Help manual as well.
I will let you know when the build is ready for download.
