a very strange and probably harmless issue :
When opening extras/spat5.overview
→ OSC tab
click on spat5.osc.route to open .maxhelp :
Max window returns this error : "arguments must be symbol "
If I create a spat5.osc.route #1 #2 #3
in a new patcher : no issue
If I create a spat5.osc.route #1 #2 #3
in the faulty .maxhelp opened as described above : error
If I open the maxhelp by right-click spat5.osc.route → Open spat5.osc.route.maxhelp : no issue !
100% reproducible in Max8 & Max9, macOS & windows, with spat5.3.4
