If I'm reading your comments correctly, you are using a Favorites list that you created. However, if that list was correct, you would not be having this issue. If you sincerely want help resolving this, then you need to provide a more detailed description of your programming. It would be best if you attached a copy of your programming file. Follow the instructions below on how to create and post a copy of your file. The file will be an *.hpe file, exported from Sentinel.
Attaching an *.hpe file to a post
Use Sentinel to "read from scanner" if you have made changes on the scanner that were not also made in Sentinel. If nothing was changed only on the scanner, proceed to the next step.
Click on the drop-down File menu.
Select export the resulting Favorites list(s) into an *.hpe file.
Sentinel will ask you to select the list to export, and then you can choose whether to export all of the systems, or select only the ones to include. Be sure that you include the system that the scanner is getting stuck on.
Then, attach that to a post and upload so that we can take a peek & see if anything is out of place. The Export function is listed under the File drop-down menu. If you have more than one list, export each Favorites list separately.
Note: To upload an *.hpe file, to the Forums, you must change the file extension to one acceptable per forum requirements. To do that, note where your exported *.hpe file is saved on your PC.
Using Windows Explorer, find the file.
There are two ways to do this. You can either change the file extension itself, or compress the file using
7-Zip or another file utility. The *.zip file extension can be attached to a post and uploaded to the Forums.
Or, using Windows Explorer, rename your file one of these two ways:
For illustration, let's call your exported file '
MyFile.hpe' (without the quotes).
<Right><Click> on the file & choose Rename from the pop-up menu.
You can then rename your file to
MyFile.txt, or
MyFile.hpe.txt in order to attach it to a post. Whoever views the file will need to reset the file name back to
MyFile.hpe, then it can be imported into Sentinel for viewing.
(You can also use Windows Explorer. <Right> click on the *.hpe file you exported. Then, from the pop-up menu, select
Send to and choose the option to add the file to a compressed folder. That compressed folder can be attached to a post here in the forums.)
This way, someone can take a look at your file, and make a suggestion as to what needs to be added or changed.
