Hello,

When we run this code the application in production (on many client systems) is hanging the application.

         if (style == 1)
                                        {
                                            if (System.IO.File.Exists(@"styles\black.isl"))
                                            {
                                                Infragistics.Win.AppStyling.StyleManager.Load(@"styles\black.isl");
                                            }
                                        }
                                        else if (style == 2)
                                        {
                                            if (System.IO.File.Exists(@"\styles\silver.isl"))
                                            {
                                                Infragistics.Win.AppStyling.StyleManager.Load(@"styles\silver.isl");
                                            }
                                        }
                                        else if (style == 3)
                                        {
                                            if (System.IO.File.Exists(@"styles\blue.isl"))
                                            {
                                                Infragistics.Win.AppStyling.StyleManager.Load(@"styles\blue.isl");
                                            }
                                        }
                                        else if (style == 4)
                                        {
                                            if (System.IO.File.Exists(@"styles\green.isl"))
                                            {
                                                Infragistics.Win.AppStyling.StyleManager.Load(@"styles\green.isl");
                                            }
                                        }
                                        else if (style == 5)
                                        {
                                            if (System.IO.File.Exists(@"styles\Claymation.isl"))
                                            {
                                                Infragistics.Win.AppStyling.StyleManager.Load(@"styles\Claymation.isl");
                                            }
                                        }

We have been using these ISL's for years but this has only started happening recently. 

We are using this version of the DLL:

18.1.20181.88

Thanks for the help,
