Hello gloucks,
this issue might be caused by periodical checking of license by CodeWarrior IDE. I'd suggest you to display the value of variable LM_LICENSE_FILE. (e.g. type "set LM_LICENSE_FILE" in Windows Terminal Window)
If the LM_LICENSE_FILE variable is not empty then CodeWarrior first tries to get the license from the paths stored in this variable. If a path refer to remote directory then it could take few second to check the directory. Therefore I'd suggest you either
completely delete LM_LICENSE_FILE (in case you don't use other tools that are based on FlexLM licensing technology)
or
paste path to your local CodeWarrior license.dat into LM_LICENSE_FILE as a very first item
