Hi,
I haven't tracked down the exact circumstances for this or whether it is caused by WindowsBlinds or WindowFX yet (or a combination of both).
I often get a phantom Compose window left behind after I send an email from Thunderbird. The window appears to close but if I minimize Thunderbird (from maximized state) there will be this window frame hanging about which cannot be closed and whose contents just copies what was previously on top of it.
