If you confirm it is working as designed, no problem, I just wonder why this is not the default option, as it makes very surprising to lose windows. Where is HTTP Monitor UI ? Hello, Once HTTP Monitor is launched in Single panel Workspace mode, I launch a test and then I cannot find the monitor panel any longer. Nor can I stop it to release the listening port ! So the only workaround I found is to stop ReadyAPI, then restart and switch to Tabbed desktop mode. Is this the only way ? It is rather inconvenient. Some tests are not reentrant, etc. Thanks in advance, Philippe Solved
