my OS is windows xp/32 . when i replace the new thinBasic_UI.dll which have size 170kb with the original thinBasic_UI.dll size 156kb i can run again the RichText control.
if the thinbasic update needs dropping support for richText in winxp then thats okay , i use usually the TextBox which is usually easier to use than RichText. i prefer the Continuous canvas feature than the rich Text.
in fact i have windows 7/64bit installed in the same machine but i don't use it, my brain is hard wired with windows xp like millions of other people
