I've researched this using "The Google" and had a few hits but nothing that's worked for me so far. The problem is that the Patch Tool seems to be permanently stuck in *transparent mode* even when that box is not checked. I've tried deleting the tool preferences both by restarting PS while holding down ctrl/alt/shft (5~6 times in a row) as well as going into the gizzards of the adobeCS3 folder in documents and settings and removing the tool pref file and then rebuilding it. All to no avail. I don't know for sure when the problem started because I don't use the Patch Tool that often but I do know that it used to work correctly. I did just recently install x-rite i1 software and calibrate my monitor. I suppose I could go the additional step of uninstalling that and trying the Patch Tool again... ugh!... but I thought I'd ask here first.
