We've now hit this tx.sap prompting issue with Windows 8.1 and IE11 devices
Note 604324 version 18 has detailed instructions to build the same registry edit as Thomas has provided in the zip file above which is great.
What is missing though per the note in step #1 for ie9 and above states to apply MS12-037 KB2699988 in a Windows 8.1 environment - it's just not possible.
Anyone else run into this yet and did you get around it?
we've tried this with both SAPGUI 7.30 PL6.1 and SAPGUI 7.20
Thank you in advance
