Repeated svchost.exe errors linked to wblind.dll

I've been noticing periodic error messages popping up that seem linked to WindowBlinds 5.0.1. The messages contain the following details:

 Error signature

     szAppName : svchost.exe     szAppVer : 5.1.2600.2180     szModName : wblind.dll
     szModVer : 5.0.1.0     offset : 00033076    

WB will be running afterwards, and it reports the following system information:

WindowBlinds 5.0 System Information Report:
