Kernberg, Thanks for posting. If possible, please send in a copy of the Brain which contains the Thoughts that cause the problem to (email@example.com) referencing this post. Please clearly indicate what Thoughts you are copying and pasting which cause the problem. We have been attempting to reproduce the problem by copying and pasting Thoughts between several Brains in version 184.108.40.206 but have not been able to reproduce the problem you run into. If you are not using version 220.127.116.11 please update to this release to see if the problem persists.
If you are unable to send in a copy of your Brain. Please reproduce the problem then send in a copy of your output.log file directly after closing down PB from your task manager. In order to generate a copy of your output.log file, right click PersonalBrain in your start menu then select the option "Run this program as administrator". You can find the output.log file in the "Program Files\PesronalBrain" folder on your system.
