When i create a new drawer with Dopus, it can't create it's icon. I get an "DOS error code 303 - buffer overflow". The same occurs with the "add icon" function in Dopus.
I had the same problem using DOpus4.17pre19 altogether with icon.library 45.1
The other day (yes, really) I updated icon/wb libs to its latests version, thanks to the bb3-unofficial post here!
now using icon.library 45.4 i have no longer such problem.
I'm still using the same DOpus4 version, since ages ago indeed.
hope it helps... (try that dopus version)
