Right click in textgridsss2 removes previous multi-selection

Hello Martin,

thanks for your help. I saw this attribute but since the documentation says “false” is the default value, I did not bother about setting it to “false”. But the behavior is different if you leave it empty or if you set the value to “false”. Maybe you could add some remark in the documentation.

(By the way, the version I am using is 40_20060908)
