As expected there are some translations cut off in WinMerge 18.104.22.168. I found the following problems at least in the German translation:
* IDD_PROPPAGE_LARGE -> IDC_SCROLL_CHECK
* IDD_PROPPAGE_CODEPAGE -> IDC_CP_CUSTOM
* IDD_PROPPAGE_EDITOR -> "Tab size:"
* IDD_PROPPAGE_COLORS_WINMERGE -> "Selected Word Diff:"
I fix the IDD_PROPPAGE_LARGE and IDD_PROPPAGE_CODEPAGE dialog allready in the "PO_translations_test" branch.
