java - Scrolling SWT Table is slow when running with exe4J -

-

i have swt desktop app distributed using install4j , runs under exe4j.

the app contains table displays list of documents downloaded server. thread handles download , makes call-backs select current row , update row icon when download complete.

this works fine in ide (eclipse) , when start app clicking on jar.

when running installed package runs slower. noticable when sort table. download schedule different order of table items and, when items selected, table scrolling , down show current item. scrolling blocks 2 seconds , large parts of table not drawn completely. logging suggests delay in waiting syncexec() run.

what be? why run fine when started directly not in exe4j?

i mailed support chaps , said 'it related fact executable has xp manifest while java.exe excutable not'.

has else had kind of problem?

just heard support.

they suggested following:

then must application manifest. don't need mageui, can edit

[install4j installation directory]\resource\manifest[.64]

and remove

from file, compile project again.

works dream. problem solved.

must here i've used support in past , have always been helpful , prompt. thanks!
