Hi Alex, dear list, I did again some testing. Original software by Claron Technology correctly identifies the tool I want to use for testing my plug-in. Correctly means, when I start the delivered demo application and enable marker processing mode, the software recognizes the marker and displays the corresponding name. Next thing I tried is using MicronTracker with the IGT example as Alex recommended. Selecting the toolfile for the recognized marker caused IGT example to hang up caused by "Grab frame time out" messages.
So far I got the following facts: 1. There is no hardware problem 2. My toolfile is correct 3. My m_Source member shows added tools when debugging 4. IGT example functionality and my own plug-in crash with same messages. Where could be the problem?
