I installed JasperServer 3.5.0 in a windows Vista environment.. and it runs fine right after installation. However , If I try to run it subsequently ( say after a boot up), it starts tomcat window etc, then pulls up a browser window but just sits there in a busy cursor mode, not ever starting the server. I tried the start, stop , restart options to no avail. Yet, if I uninstall and reinstall again it will start at the end of install ( if the checkbox is checked to start server... Any ideas on why? any help would be appreciated thanks in advance Stu
