Hi
I'm using the custom filtered lookup for CRM 4.0 which I thought was working fine until I discovered that every so often when I click on the lookup I'm presented with an empty lookup window containing only a hash sign #.
The way I've applied the custom lookup was to edit the lookupsingle.aspx file and drop it in a newly created folder at inetpub/wwwroot/ISV/CustomLookup. This edited lookupsingle.aspx file is then called from the onload() event of the CRM entity.
I've tried to find a solution for this online but all I can find is to turn of the XSS filter which has no affect at all.
This is happening on both IE8 and IE9.
Has anyone been able to resolve this issue previously?
Thanks in advance
David
