Grouping is incorrect on 64-bit server

I have a report that displays correctly in 32-bit development workstations and when run from a 32-bit server, but not on 64-bit servers.

This report displays responses to a survey that users have submitted. It has several levels of grouping, as follows:

Administration of the survey (an individual survey can be sent out multiple times; responses are grouped by each time they are sent out)

Response Date

Respondent

Response (the header for the set of answers that are submitted when the user clicks a Submit button on the survey)

Question Number (finally, responses to individual questions are grouped by question number; some questions can have multiple responses... think checkboxes, "choose all that apply")

The Question Number group is not handled correctly in the 64-bit environment. It will print the first few items under the first question correctly, then switch to the next question, and then revert back to the first question several times.

Like this:

1 Choose all that apply: Option 1

Option 2

Option 3

2 Question 2 Text ....

3 Question 3 Text ....

1 Choose all that apply: Option 4

1 Choose all that apply: Option 5

1 Choose all that apply: Option 6

It should be:

1 Choose all that apply: Option 1

Option 2

Option 3

Option 4

Option 5

Option 6

2 Question 2 Text ....

3 Question 3 Text ....

I can provide .jpg examples if it would be helpful.

We are using the Crystal Reports Basic Runtime for Visual Studio 2008 (x64) (files with version 10.5.0.1943). I tried installing the service pack version of the runtime (files with version 10.5.1.2285) but it did not affect the problem.

Any ideas on what the problem might be or a way to fix it? I also could not find anywhere to submit a bug report; is there someplace I should submit this other than the forum?

Thanks,
