Bug in Report Designer - can anyone reproduce?

I think I've discovered a serious bug with the Report Designer, which
causes devenv.exe to take up 100% CPU and skyrocket in memory usage.
Here's how I got to it:
-Create a report with three parameters: The first two are dates (start
date and end date for a date range) and the third is a String
(employee name).
-Create a query to auto-populate both date fields.
-Create a query to fill the String parameter with values that are
dependant on the first two date parameters (return employees that were
active during the range of the two parameters, for instance).
This works okay when deployed, but in Preview Mode in Visual Studio,
after changing either of the Date parameters from their default value,
VS seems to get stuck in an infinite loop when attempting to
re-populate the third parameter with employee names.
Can anyone reproduce this?
Thanks,
Matthew Brown
Viecore IncYes, I have seen this (and like you saw that it was not a problem with
deployed reports). Once I saw that deployed was OK then I would deploy for
testing (a bit of a pain but I did not have many reports with this issue).

serious issue.
I would think anyone localizing strings within a report with RS 2000 would
have the same issue as I do. It makes the preview functionality of Report
Designer useless. I would love to have a fix for this in RS 2000.
Thanks for any help or indication of priority, good or bad,

description does not seem to have anything to do with what we were talking
about. I have not seen your symptom before (either personally or via a post
in the newsgroup). I use a small amount of custom code but mine is code
behind reports, not a custom assembly. I do know there are definitely
specific steps to be taken when using custom assemblies. I suggest posting
with a subject of "Custom assembly hangs Report Designer) and see if someone
who has used custom assemblies has any ideas.

function which calls right out to a custom assembly, which in turn returns a
string. once I have a few of these in the report the designer no longer
functions, flickering as it tries to refresh (apparently). There are
certainly steps to be taken with respect to referencing and securing a custom
assembly, but I don't think a configuration problem with the custom assembly
would cause this behavior in the Report Designer.
Instead, it seems that the Designer is trying to refresh its fields very
often, and when several fields call out to a custom assembly, the designer's
desired refresh cycle is faster than all of the calls can be completed (?).
Thanks for your help.
