Thank you, @DeLub .
What is your Hookmark version(in Hookmark about window) and macOS version?
Do you have clipboard manager running? I found I need quite Paste.
If you open an email in Spark, then copy the following script to Script Editor, run the script, what the output?
Thank you
Script
tell application "Spark Desktop"
activate
end tell
set the clipboard to ""
delay 0.1
tell application "System Events" to tell process "Spark Desktop"
keystroke "l" using {command down}
delay 0.2
repeat 10 times -- poll clipboard for ~1 seconds. Sometimes set x to the clipboard throws exception
try
set theUrl to the clipboard
if theUrl is not equal to "" then
exit repeat
end if
end try
delay 0.1
end repeat
end tell
return "[" & theUrl & "](" & theUrl & ")"
