AutoHotKey script fails after first use - autohotkey

Question

I am working with a Help file as a Word 2007 document. I need to update the screenshots as I go through, so I'm trying to get AHK to select the 'Change Picture' option from the right click drop down menu when I press my key combination. I've got the code, and it works perfectly... the first time I use it. After that, I only see the right click menu flash and disappear. I suspect that the script from Send {Down 4} on is not executing because I can just barely see the 'Cut' option highlighted, but the selected image is not cut from the document, indicating that the Send {Enter} is also not being executed.
I cannot find anyone else who seems to be having this problem. If I manually reload my script, it works fine again, but only the once. Then it's back to flashing the drop down and nothing else. Any help would be greatly appreciated. I'm trying to get this process down to as few clicks as possible, but it's getting to the point where I'm wasting more time trying to solve my macro problems than I would just doing it the slow awkward way.
My script as it is now:
^!z::
Send +{F10}
Send {Down 4}
Send {Enter}
return
For clarification's sake:
When I remove everything following Send +{F10} and then use my hotkey, I get the right click menu displayed and not flashed, but again, only the first time I use it. After that, the menu goes back to flashing on the screen once. To compare, actually pressing Shift and {F10} displays the right click menu, and it does not disappear on lift.
If I move all three Send commands into one line to get Send +{F10} {Down 4} {Enter} The script executes the 'Cut' option from the right click menu, then moves the cursor down 4 lines and then sends the {Enter} keystroke. This set of actions works after the first use of the script, unlike previous instances.

Answer 1

In my copy of Word, the control key causes a secondary 'Layout Options' menu to pop up if there is an image selected. While I'm not sure why it's working for you the first time but not subsequently, when I test this at my end it works if I change two things:
Use mouseclick, right instead of Send +{F10}
Change the shortcut modifier from shift-ctrl to Win, i.e. set it to #z

You can try sending the keyboard shortcut instead of down command
SetBatchLines, 1
SetKeyDelay , 100 ; in miliseconds, keep increasing until your pc can hadle it
!x:: ; your hotkey in my case alt + x which is similar to ctrl + x for cutting text
Send +{F10}
Send {t} ; use the cut keyboard shortcut, for word should be 't'. if for some weird reason isn't change it
Send {Enter}
return
