(code 1): toastbar.java, line 602

c.label.getparent().replaceandwait(c.label, newlabel, commontransitions.createcover(commontransitions.slide_vertical, true, 300));

(code 2): digitroller.java

protected void copytoclipboard () {         clipboard.copystring(stoken);         toastbar.showerrormessage("copied " + stoken, 1000);     }

copytoclipboard() invoked actionlistener:

btncopy.addactionlistener((e)-> {             this.copytoclipboard();         });

after displaying exception details in dialog app freezes or stops animations it's own decision. extremely simple way crash application.

this seems bug, added potential workaround here.
