Like Houdini the Helper window in the Disassembler has done a vanishing trick. I moved it and it acted like it was docking itself then just nothing, it was gone tried the window menu and it was still check marked and clicking it again didn't help, reloading the MHS didn't help and the Show All option didn't work either. So not sure what I did but it officially hates me lol.
[EDIT]
Deleting the DefProf.ini file and restarting MHS seemed to fix the issue, not sure why it's happening though or where it's going...
