Hi dmitryl,
Please always use the latest version of EmEditor Professional — currently v11.0.5.
This “Do you want to terminate the current tool job?” message appears because the previous external tool job has not been finished before you try to start the next external tool job. It is a good idea to properly finish the job before you start the new job.
If you can’t finish the previous job, you can disable this message by adding the following registry key:
HKEY_CURRENT_USERSoftwareEmSoftEmEditor v3Common
PromptTerminateJob
REG_DWORD: 0
Thank you!
