Hi Krijn,
I have tested for this in v2.0.5.0 using the sample present in the directory ...\Syncfusion\Essential Suite\2.0.5.0\Tools\Samples\Tabbed MDI Package\Advanced\AdvancedTabbedMDI\VB, and the browsing arrows were displayed correctly as shown in the
screenshot attached. Please let me know the version of Essential Suite that you are using. Thanks for your cooperation.
