How do I get you a full working version of the database and app without uploading it here? I can't have my code/database open to the public.

It is the GetScheduleEvent that has the issue. 

ISDataSource = 1.0.1500.212

WebScheduler = 3.0.1000.130

It would be difficult to provide a sample due to the nature of the data but I have attached the application anyway in hopes you will be able to find a config or application issue.

Ok I downloaded the latest of all the controls on the production server and now everything works with the Allow 32bit Applications=False. However, I am still experiencing slowness and I am very concerned. Here is the current application details. The aspx page has an iFrame and the iFrame is loaded wth the path to another aspx page (with querystring params) that contains the WebScheduler. Any issues with this?

When running it locally in a development environment I get multiple js errors which I think is the reason for the slowness (however the webscheduler works).

I get 3 of these errors:

Null is null or not an object:

var vac823 =vbcc15.split("||IS||")

Any suggestions?

I also have this error:  Attempted to read or write protected memory. This is often an indication that other memory is corrupt

and I was able to fix it by setting Enable 32-Bit Applications=True but my question is WHY? Why do I have to run this in 32 bit mode on a 64 bit machine? Doesn't make sense...besides it is much slower than it should be. Please assist.
