Hi there,
Application: Kleopatra (Certificate Manager and Unified Crypto GUI)
Version: 2.1.0
KDE Version: 4.1.4
I am a developer who is working on a piece of software that accesses the Cl=
ipboard.
I am experiencing a problem whereby when trying to access the Clipboard an =
ExternalException is thrown with the following error message: 'The requeste=
d clipboard operation did not succeed'. As a result, I did some diagnostic =
work to try to work out which application was locking the Clipboard. There =
seem to be a number of different applications that sometimes lock it (presu=
mably whilst they have access to it).
However, the worst offender seems to be Kleopatra.exe. By 'worst' I mean it=
seems to persistently lock the Clipboard and thus blocks our application f=
rom accessing it. We are not actively using Kleopatra when this problem occ=
urs; it is just running in the background. Also, interestingly this problem=
does not always seem to happen; sometimes Kleopatra doesn't seem to access=
/lock the Clipboard.
I was wondering if you might know why this is and if there is anything we c=
an do to prevent Kleopatra.exe from persistently accessing the Clipboard?
Thanks,
Andy
