The RecordSource was being defined in the activate of the page that the grid was on instead. As soon as I changed it on the grid everything worked fine. I'm not exactly sure at what point the RecordSource needs to be available for the GridHighlighter to handle it, but for me just having a default set at development did not disrupt the functionality of the app and allowed the class to work as intended.

Hi Renoir,

Thanks for letting me know. I just added the code to GHL to handle situations like this. The thing is that I just can't sit, prepare the test cases for all possible usage of the class and test everything.
I believe the job like this would be similar to what JohnK will be getting the big bucks for at Microsoft soon. :)

I will post the updated version this weekend. There is another GHL code change that will be in it too. Thanks to Raymond Humphrys, who told me about that. Raymond was using GHL in all forms, but just one form (working with GHL properly) sometimes was giving these "Invalid Dynamic... Expression" messages on the form closing. This is really the grid issue, not GHL issue, but some extra code in GHL can make the grid destroying process more reliable.

Since on the form closing GHL gets destroyed before the grid, the code in GHL Destroy() method will reset all Dynamic... expressions to nothing, so when the grid in turn gets destroyed there will be no Dynamic... expressions sometimes causing grief.
