Hi Millzy,
Thanks for the report. Haven't heard of anything like this before, so I'd like to investigate.
Any chance you could send me the following file via PM please (assuming it exists - if it doesn't, that may be part of the problem)?
C:\Users\[user]\AppData\Roaming\Cakewalk\Cakewalk Core\Lenses\Default.lns
Also the custom lens file that you're stuck on, which will be in here somewhere:
C:\Users\[user]\AppData\Roaming\Cakewalk\Cakewalk Core\Lenses\User\
I might be able to reproduce and fix it with access to those files.
Thanks again,
Ben
