Just klick on B and cycle through options. Works as it should.
I did it, but the transparent mode doesn't work for me.
Strange that v2.26 works for you, since I can't replicate this error I can't try to fix it. Tell me about your setup and AmigaOS version etc. You did add GetWBPatter to c: ?
Yes, I have GetWBPatter. I use OS 3.2.3
2.28 only has the difference of using GETWBPattern and it allows WBPattern to have backdrop save on other drives than sys:
I might found something strange, try v2.28b
