I've built a scheduling program with an adp front end and a sequel backend. In a number of locations I use the activeX calendar 10.0 control to facilitate point and click population of date textboxes (i.e. scheduling to and from) I sent distributed the application to our LA (Brazil) and the calendar grid displays blanks for some users...I asked local IT support to make sure their regional language settings were all the same and still no dice??? I coded in a registration tester and I didnt get an error? Does anyone have any thoughts??? oh yes funny thing it works fine in Singapore and the UK?
