switching from 9.1 and 10.0 requires browser 'reset'

Hello, I want to share this difficulty I'm encountering in switching from 9.1 to 10.0.

I start the embedded tomcat in the SDK (SmartClient_v100p_2014-10-16_Evaluation), then do a 'Reset Safari', open the url of the SmartClient_Explorer, and then open the developer console - everything is fine - and I close the developer console.

Then I shutdown the embedded tomcat in the 10.0 SDK, and start that of the 9.1 (SmartClient_v91p_2014-10-05_PowerEdition), refresh the SmartClient_Explorer in Safari, it loads the 9.1 SmartClient Explorer, but if I open the developer console it still tries to load the 10.0 developer console (so it raises an error, see below)!

Code:

Error in call() - unable to resolve sendChannel

    MessagingDMIClient.call(_1=>"getGlobalLogCookie", _2=>Array[0], _3=>anonymous())

    saveState(_1=>undef)

    anonymous(target=>null, eventInfo=>undef)

    [c]Page.handleEvent(_1=>null, _2=>"resize", _3=>undef)

    [c]EventHandler.$78p(_1=>"landscape")

    [c]EventHandler.$hr(_1=>true)

    [c]Canvas.checkForPageResize()

    [c]Class.fireCallback(_1=>Obj, _2=>undef, _3=>Array[0], _4=>[Class Canvas], _5=>undef)

    [c]Class.$cm()

    ** recursed on [c]Class.fireCallback

Stack trace:

Why does it happen ? Is it possible to avoid the need for a browser 'reset'? I've never experienced something like this with previous versions.
