After working in InkScape for whole day & after playing with preferences of InkScape, It started to gave me trouble with few tools & option such as while using ‘Paste in Place’ it seems that option was not working properly.
But later I found work around that,
I did two + one things,
Trash InkScape Preferences file from Your Hard Disk, Path: Macintosh HD/Users/YOUR-USER-NAME/Lybrary/Preferances/inkscape-preferances.plist
Delete Cache Folder from Your Hard Disk, Path: Macintosh HD/Users/YOUR-USER-NAME/Lybrary/Cache
After Deleting ‘Cache’ Folder from your account’s (Your Mac OSX User Account) ‘Library’, InkScape seems to be works perfectly
With Disk Utility I Verify & Repaired Disk Permissions of ‘Macintosh HD’ System Drive.
Now it seems to be InkScape working properly…
Problem has gone now…
Thanks & Regards
