Problem with TBS3.0 and MAc OS 10.4????


I recently upgraded to a Mac G5 with OS 10.4 from a G3 with OS 10.3 and ever since my timeline functions are very buggy. Pegs act strange. For example I click on a peg to try to move an attached element but instead when I move it moves a different element. Are there problems with TBS 3.0 and Mac OS 10.4? It’s so frustrating I can’t work at all because nothing is working how it is supposed to. Has anyone experienced anything like this? Am I doing something wrong?

Thanks so much in advance for your help,
