I think when u uninstall iMesh,it should give u an option of choosing the components to uninstall.U can check the Media Tool bar and uncheck iMesh to uninstall the toolbar.If it doesnt work,then there should be a separate folder for the toolbar in the folder where iMesh is installed.An uninstall icon should be there,probably.If even that doesnt work,then u should uninstall iMesh and reinstall it,only this time,u should uncheck the option to install the toolbar.Hope one of the above ideas work.
