I've got the same problem here and in addition I've noticed that there are a dozen copies of the controls that make up the grid in the Designer.Vb / Resx files. The grid control seems to be orphaning the grid sub-controls and recreating with a new sequence number during some undetermined development event. Only the unbound columns are not being recreated with the newly updated sequence number.
Don't know if any of that helps at all but some of my observations on this issue.
Do you all have any idea of the time frame for the release of a patch for this issue?
Thanks,
Stephen
PS my setup is 32bit and not 64bit like Артем.
